Be still my heart and cut me the largest slice of this homemade Cookie Cake! This chewy chocolate chip cookie cake is inspired by the mall favorite (shout out, Great American Cookie Co.!), but tastes so much better than store bought.

This iconic dessert has held a dear place in my heart since childhood, when I begged my mom to buy me a cookie cake I could bring to school on my birthday.

Is cookie cake better than cake for a birthday? I certainly thought so!

(And considering how many times my friends have requested this beloved giant homemade cookie cake for their own birthdays, I’d say there’s agreement.)

Plus, the kids who brought the Great American chocolate chip cookie cakes to school were the coolest.

5 Star Review

“Made this cake for a friend and she loved it! There was just enough chocolate frosting and all of the flavors came together nicely.”

My inspiration for this homemade cookie cake is the original Great American Cookie Company recipe.

I still adore cookie cake as much as ever, but now I prefer to make it myself for a few reasons:

  • Simple Ingredients. This is a recipe for real, homemade chocolate chip cookie cake from scratch, no cake mix or canned frosting to be found.
  • THICK. I wanted this to be a cookie cake. Whereas store bought cookie cakes are thin, which does not feel very celebratory, this one stands tall and proud.
  • Sturdy AND Chewy. You can pick up a slice to snarf with your fingers, but it is still tender and melts in your mouth.
  • Less Expensive. A store-bought cookie cake from Great American starts at $37. Make it from scratch for a fraction of the cost, with ingredients you already have.
  • Customizable. Why be limited to a premade Great American Cookie cake, or your typical grocery store cookie cake? With this homemade giant cookie, you can add your own mix-ins and decorate anyway you like.
  • Way Better Frosting. Forget that sickeningly sweet store frosting. This fudgy frosting is creamy and rich, but won’t give you a toothache.

The Best Pan for Cookie Cake

You can bake cookie cake in a 9-inch pie dish, 9-inch round cake pan, or my favorite, a 9- or 10 inch springform pan. The edges of the pan are removable so you don’t need to worry about the cookie cake sticking.

While you can buy cookie cake pans online, they aren’t necessary for a great homemade cookie cake.

The Ingredients

  • Flour. I used part all-purpose flour and part white whole wheat flour in this recipe. If you don’t have white whole wheat flour in your pantry, feel free to use only all-purpose flour in this recipe.
  • Nutmeg. A pinch of nutmeg is my secret ingredient to this cake’s extra special flavor.
  • Egg + Egg Yolk. The binding agent that holds our giant cookie together. I added one extra yolk to give the cookie just the right amount of richness.
  • Milk. You can use any milk you have on hand, but the higher the fat content, the creamier the results. I used whole milk, and it was perfect.
  • Pure Vanilla Extract. A MUST in cookie cake recipes.
  • Chocolate Chips. If you’re a fan of chocolate, this chocolate chip cookie cake recipe is perfect for you. This cake has more chips than you’d dare call appropriate, and you’ll love every single bite. A cookie cake is a cookie after all.
  • Frosting. While it’s optional, I guarantee that you won’t be disappointed with a frosted cookie cake. You can pipe the frosting or spread it with an offset spatula.

This giant homemade cookie cake recipe is rich, chewy, and tastes way better than store bought! Perfect for birthdays and special occasions.

Prep: 20 minutes
Cook: 20 minutes
Total: 40 minutes

Servings: 12 slices


For the Chocolate Chip Cookie Cake:

Chocolate Fudge Frosting (optional):

  • 1 1/2 cups powdered sugar plus 2 tablespoons
  • 1/4 cup unsweetened cocoa powder
  • 6 tablespoons unsalted butter softened to room temperature
  • 2 tablespoons whole milk*
  • 1/2 teaspoon instant espresso powder optional—it will intensify the chocolate flavor without making the frosting taste like coffee
  • 1 teaspoon pure vanilla extract
  • Pinch kosher salt to taste


  • For the Chocolate Chip Cookie Cake: In a medium mixing bowl, whisk together the all-purpose flour, whole wheat flour, baking soda, and nutmeg.
  • In the bowl of a standing mixer fitted with the paddle attachment or a large mixing bowl with a hand mixer, beat together the butter, brown sugar, granulated sugar, and the salt on medium speed until smooth, about 3 minutes. Add the whole egg, beating for 1 minute and stopping to scrape down the bowl before adding the egg yolk. Beat for another minute and scrape down the bowl again. Beat in the milk and vanilla.
  • Reduce the mixer speed to low, then slowly add the dry ingredients, mixing just until the dough comes together and the flour has disappeared. Add the chocolate chips on low speed, finishing with a few stirs by hand as needed.
  • Lay two large sheets of plastic wrap down on the counter so that the long sides overlap slightly and you have one large, wide sheet. Scrape the dough into the center, then spread it into a thick disk. Fold the edges of the plastic up and around the dough to wrap it completely. Refrigerate for at least 1 hour or up to 3 days.
  • When ready to bake, preheat the oven to 350°F (if using a clear glass dish, reduce temperature to 325°F). Generously coat a 9-inch springform pan, 9-inch pie dish, or 9-inch cake pan with baking spray. Press the dough into the pan in an even layer. Bake for 20 to 25 minutes, until the top is lightly golden brown and a toothpick inserted in the center comes out clean. Check at the 15-minute mark—if the cookie cake is browning too quickly at the edges, loosely tent it with foil. Remove from the oven and place the pan on a wire rack to cool completely.
  • Meanwhile, make the Chocolate Fudge Frosting (optional): Sift the powdered sugar and cocoa powder together into a bowl. In a separate bowl, beat the butter on medium speed until light, smooth, and creamy, about 2 minutes. Reduce the mixer speed to low, then add half of the powdered sugar and cocoa mixture. Add all of the milk, espresso powder, and vanilla. Beat to combine, then add the rest of the dry ingredients and beat for 2 minutes until well combined. Taste and add a pinch of salt if the frosting seems too sweet.
  • Frost and serve: Once the cookie cake has cooled, run a sharp knife around the edges to loosen it, then transfer it to a serving dish (you can also serve it directly from the pan). If desired, decorate with the chocolate frosting.



  • *You can use any milk for the frosting and cookie you like. I prefer something with some fat in it (such as whole milk, cream, or half and half) because it’s a small amount and results in a richer, creamier frosting.
  • TO MAKE AHEAD: Prepare your cookie dough ahead of time, and store it in the refrigerator for up to 3 days or freeze it for up to 3 months.
  • TO STORE: Cover and store leftovers at room temperature for up to 3 days.
  • TO FREEZE: Store the baked cookie (frosted or unfrosted) in the freezer for up to 2 months.

  1. This recipe is PHENOM! I did not use the nutmeg (didn’t have any), but I did do the half white whole wheat flour. Made it for a party and everyone was raving and I was sad I shared it at all lol. So easy as well. Definitely going to be a staple!5 stars

  2. I am testing out cookie cake recipes for my son’s upcoming birthday party. At first, I wasn’t sure about the nutmeg when reading over the recipe, but it does add a nice flavor. I used all-purpose flour because that is what I had on hand. I think this is the winning recipe. I keep going back for more! I love the frosting. It has just the right amount of sweetness and great flavor!5 stars

  3. This recipe is so good! Our local grocery store couldn’t make me a cookie cake for my son’s birthday so I decided to make it myself and found your recipe. So delicious and easy to make. Thank you so much!!5 stars

  4. I made this for my daughter’s birthday and it is so delicious! I added walnuts per her request and used vanilla buttercream instead of chocolate fudge and it was so good.5 stars

    1. Hi Jane, I wanted to make this recipe for my son’s birthday this weekend. How did you do your vanilla buttercream? I also wanted to do it with it. -Jess

  5. This cookie cake recipe is amazing! Made it for my sister’s birthday and everyone could not get enough. They raved about it being perfectly soft in the middle. I will definitely be making this again!5 stars

  6. Oh my gosh YUM! My son asked for a cookie cake with icing so I googled and liked the picture you had, so I chose this recipe and I am so glad I did! It’s amazingly good!5 stars

  7. Made this earlier for a friend’s birthday party and everyone liked it. I baked mine for about 22 minutes and let it sit in the cooling oven for an additional 5 minutes.5 stars

  8. I made this for my daughter’s birthday and it was so easy and delicious! I used an 9 inch pan. The cookie cake is soft and chewy. It stayed soft for 4 days. The frosting was perfect; I just put it in the fridge for a few minutes so it could set up a little firmer.5 stars
